Export to mp4 without loss of quality

Recommended Posts

I love using VideoPad, it is so intuitive, but my problems are with exporting to mp4. I would like advice about which specific settings to use. 
I normally use resolution: 1280x720 
Compressor: mpeg
Video quality: default
Lossless export: autodetect
VRF: Max 29.970

But it is not as clear a resolution as I would like. But if I use a higher setting it often creates a file that is nearly 900MB ! 

I create videos that combine still images with some video, but usually no more than 12 minutes long.

If I use H264 instead of mpeg it triples the size of the file. Could you advice me on export settings that  create a good quality result but without resulting in such a huge file?

Just to clarify I use a Macbook, so use macOS High Sierra, rather than Windows.

Upload an exported file that doesn't play well to a free server, get a public, non-restricted, shared link and post it here.  Someone will check it out.

There should be several compressor and quality options available in the export window.  Test them.

Hi,

According to what says about MPEG-4 vs H264, the latter one is compressing 1,5-2 times better with at least same quality. Your problem might be that you leave to VP to decide about the quality -  the default value is rather high. As borate already said, try lower settings. You can check bitrate of your MPEG-4 compressed video and put the same bitrate in Export - File format - Video Quality/Bitrate. If you choose H264 with same bitrate as MPEG-4, you should get same file size but better quality!

Thank you, although when I click on video quality/bitrate it just gives me the dropdown options of high quality down to very low quality. The bitrate is actually 1.08 mbit/s but I can't seem to be able to input that number.

Thank you so much for your reply. I clearly didn't scroll down far enough! Much appreciated. Interesting though, with even using these settings that it results in a file that's over 500MB. That still seems very large for a 14 minute video (with a few images added). As I've said, using the mpeg4 compressor does reduce the size, but the quality is nowhere near as good as using H264.

Mp4 export using H264 defaults (including suggested frame rate) in Windows produced a file of 264 to 410MB on several runs.  The PAL (25fps) export was 390.

Mp4 export using the MPEG4 compressor chalked up  249.   AVI export using MPEG4 resulted in 266.

Each test used version 8.63 at1280 x 720.  Output quality was consistent with the source files.

Thank you so much for looking at this for me. However, I have just exported this same file with these settings below and it has resulted in a file 810.4 MB !

Preset: Custom. Compressor: H264. Default Quality. Lossless export: auto detect. Resolution: 1280x720. Variable Frame rate (Max 25fps)

It says estimated file size is 411.05. But, as I say, the resulting export was approx twice that size!

Using the mpeg4 compressor it estimates 164.42MB and the resulting export is 252.6MB. (quality not as good as H264 though)

Both times big difference in estimate and actual size. And something is clearly going amiss in the exporting, as 810MB is too large. I'm using the non-commercial 8.60 version.

Estimates are historically inaccurate.

Can't test MAC exports here, but the Windows 10, VP version 8.65 (beta) mp4/H264/45 fps result is 412MB.  PAL was 392.

As suggested by janusz_wol, try lower quality/bitrates to see if they sacrifice too much quality.  Here, low and medium quality PAL came in at 82MB and 190 respectively.

Considering that the source wasn't HD, the medium rate looks quite acceptable here ... but that's a subjective judgment.
